The LTC8811A family of single-channel amplifiers features a maximized ratio of gain bandwidth (GBW) to supply current and is ideal for battery-powered applications such as portable instrumentations, portable medical equipments, wearable fitness devices, and wireless remote sensors. Featuring rail-to-rail input and output swings, 15-kHz bandwidth of combined with ultra-low supply current (typical 600 nA at 5.0 V per amplifier) and low noise (6.3 μVP-P at 0.1 to 10 Hz) , the LTC8811A family is an excellent choice for precision, cost-optimized, “Always ON” sensing applications. The robust design of the LTC8811A amplifiers provides ease-of-use to the circuit designer: integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high electro-static discharge (ESD) protection (5-kV HBM). The LTC8811A amplifiers are optimized for operation at voltages as low as +1.7 V (±0.85 V) and up to +5.5 V (±2.75 V) over the extended temperature range of −40 ℃ to +85 ℃. The LTC8811A (single) is available in both SOT23-5L and SC70-5L packages.
